Unscrew the hose and spigot to ensure they are not clogged. After that, reattach them securely. Examine the water supply feed line beneath the sink. Even if the dishwasher is turned on, it cannot fill with water if it was accidentally turned off for any reason.

Examine the water system line for bends. If you come across one, turn off the water and remove the hose and kinks. Reconnect the water system hose and switch the valve on. Then finally, make sure the wastewater pump, which is located beneath the filters, is not clogged.

Check with multimeter:

Finally, you can check the continuity of the inlet valve with a multimeter. After turning off the machine, remove the electrical socket from the valve. Then put the multimeter probe on the terminals.
